GRIPPING lMPLElVl ENT.

SPECIFICATION forming part of Letters Patent No. 319,017, dated June 2,1885.

Application filed March 24, 1885. (No model.)

To @ZZ whom it may concern:

Beit known that I, GEORGE C. PAYNE, a citizen oi' the United States,residing at Washington, in the District of Columbia, have invented aCertain new and useful Improvement in Gripping Implements, of which thefollowing is a specification.

My invention relates to gripping implements in which the jaws areoperated by means of two pivoted levers; and the object of myimprovement is to cause the jaws to maintain a position parallel to eachother, or approximately so, throughout their range of movement. I attainthis object by the mechanism illustrated in the accompanying drawings,in whioh- Figure l is a plan View of the implement, the full linesrepresenting the position of the parts when the jaws are closed, and thedotted lines the position when the jaws are opened. Fig. 2 is aperspective view showing the slots in the jaws and handles and themanner in which the parts are joined.

Similar letters refer to similar parts throughont both views. f

The levers A D'l and A D are pivoted at E, and the outer ends of theirshorter arms are pivoted at F F in a pair of jaws, B B. These jaws,which may be of any convenient design, are prolonged toward the longarms or lever-handles D D', and connected by pins G G with theguiding-links C C',

these guiding-links being pivoted in the slots of the lever-handles D Dby the pins H H.

The guiding-links C C are of sueh lengths and u connected with theprolonged jaws B B and the lever-handles D Dl at such points that uponopening the jaws the outward movement of the lever-handles D D at thepoints where the guiding-links are pivoted on the handles, combined withthe outward movement of the guidinglinks O C at the points where theyare pivoted to 'the prolonged jaws, will be equivalent to the outwardmovement of the short arms A A at the pivotal points F F.

I am aware that gripping implements have been made in which, byasuitahle combination of levers, the jaws are made to maintain aparallel movement. This, therefore, I do not Claim, broadly; but

That I do olaim is- In a gripping implement, the combination of the twolevers A D and A D, pivoted together, the slotted gripping-jaws B B',pivoted to the outer extremities of the shorter arms A A of the levers,and the links O C', pivoted to the rear ends of the gripping-jaws andpivoted in the slots of the longer lever arms or handles, thecombination operating to keep the faces oi' the jaws parallel.
